U.S., Canadian, U.K., Irish, Australian, and New Zealand citizens with a valid passport don't need a visa to enter Sweden if they don't expect to stay more than 90 days and don't expect to work there. If, after entering Sweden, you want to stay more than 90 days, you can apply for a permit for an extra 90 days, which as a rule is granted immediately. Go to the nearest police headquarters or to your home country's consulate. If your passport is lost or stolen, head to your consulate as soon as possible for a replacement.
